Ammunition

Remington Ammunition Is Cranking Out Ammo Once Again – They Were Bought By Vista Outdoors … But Who is Vista Outdoors?

I was surfing around and dropped by Youtube to see what new videos would pop up and there was a four day old video that was a tour of the Remington Ammunition plant. Okay, the tour of an ammo plant always catches my eye but it got me to thinking also. I knew that Remington declared bankruptcy in July 2020 and was bought by Vista Outdoor. I also knew Vista Outdoor owned a number of brands including Federal but what dawned on me was that I really didn’t know much about Vista. Well, when I have a gap like that, I do some digging and a blog post emerges.

First, here’s the cool plant tour video that kicked this all off:

What happened to Remington in the first place?

Well, rather than start with their founding in 1816 by Eliphalet Remington, let’s jump ahead to 2007. Remington was an iconic firm by that time and due to a string of circumstances including declining sales and reputational damage, they were acquired by Cerebus Capital Management. Remington was already millions of dollars in debt but went ahead and bought Marlin Firearms and Advanced Armament Corporation (AAC) – the suppressor company.

Now if you look back on it, a lot of innovation had ceased and they were milking existing product designs. They were involved in litigation, still not making money and declared Chapter 11 bankruptcy in July 2020. As a result, their assets went up for sale. Remington outdoor was split up and sold off piecemeal.

Remington Arms and non-Marlin firearms were sold off to the Roundhill Group. Remington’s ammunition business was sold to Vista Outdoor. I did some quick reading and don’t know much about Roundhill but really the focus of today’s post is Vista so let’s go there.

Vista Outdoors Started As ATK Sporting Products

Well, if we wind back the clock to 1990, a defense company called Alliant Techsystems (ATK) was spun out from Honeywell. ATK had supplied products to the defense industry for close to 50 years at that point.

In 2001 they bought Hercules Aerospace who also made Hercules brand gun power. and decided to enter the ammunition business and bought Blount Industries. The move made them the largest ammunition maker in the United States.

Bear in mind ATK was a big firm and making launch systems also – we are not talking about a small organization, Also in 2001 they acquired Thiokol who made the solid rocket boosters for NASA’s space shuttle program. I’m not going to detail the defense group but they were making missles, the Bushmaster cannon and more.

In 2012 the Army selected ATK to operate the Lake City Army Ammunition Plant (LCAAP) that Remington built in 1941. Renovations were made and quality was improved.

To give you an idea of how big the Sporting Group was – here is a list of the brands they were producing: Allant Powder, Blackhawk, Bolle Bushnell, CCI, Cebe, Champion Targets, Federal Premium Ammunition, Final Approach, Gold Tip Arrows, Hoppes, Outers, Primos, RCBS, Savage Arms, Serengeti, Speer, Uncle Mike’s, and Weaver Optics. That’s quite a spectrum – everything from ammo to sunglasses.

In 2014 ATK decided to split into two companies. Aerospace and defense groups would be merged into Orbital Sciences Corporation. The sporting products group was split off to create Vista Outdoor. The creatiion of the two was completed on February 20, 2015.

Wikipedia has a decent write up of ATK’s history if you want to read more.

Vista Outdoor

Vista was a public company from the start and subject to the pressures of the market to make money, deal with debt, promote and protect the brands it held, etc.

In 2018 they sold off the eyewear brands of Bolle, Cebe and Serengeti.

In 2019 they sold off Savage and Stevens Arms to a group of investors led by the Savage management team.

In 2020 they bought the Remington ammunition and accessory assets. This included the ammunition plant in Lonoke, AR, for $81 million.

How big is Vista Outdoor (stock symbol VSTO)? Well, in terms of sales, they are at $3.04 billion USD in 2022, up 36.08% from the previous year. Net income is positive at $473,23 million up 77.9% from 2021.

Vista does plan on splitting the company into two parts – Outdoor Products and Sporting Products, both of which will be publicly traded.

Outdoor products will include the brands: Bell, Bushnell, Bushnell Golf, CamelBak, Camp Chef, Foresight Sports, Giro, Hoppes, QuietKat, Stone Glacier and others – they have a ton actually so click here for the

Sporting products will include the ammunition brands: CCI, Estate Cartrdige, Federal, Hevi-Shot, Remington, and Speer

As a quick side comment – I didn’t realize how many sporting optics brands that Vista owned until researching this post: Bushnell, Redfield, Simmons, Tasco and Weaver.

In terms of what is new, the company’s CEO, Chris Metz was asked to resign by the board on February 1, 2023, due to a loss of confidence in his leadership. They say the parting was in good terms but regardless of how you look at it, they fired him and there aren’t public details. The firm’s CFO left back in November 2022 so there is some movement going on.

Gary McArthur, a board member, has been appointed interim CEO in the meantime until a permanent CEO is found.

So, that’s Vista Outdoor in a nutshell. Another big holding company with a ton of brands. They invested in bringing the Remington ammunition factory in Lonoke, AR, back up to speed and it is producing now. That’s good.

What will happen with the planned splitting up of the company and long-term plans, it is hard to say. When you look at the the stock price over the past year, it has fallen but it didn’t plummet with Metz’s departure so time will tell. Hopefully good things will continue to happen.

Air & C02 Rifles and Pistols

The GX CS4 Compressor Isn’t Replacing the CS3 Models – The CS4 Is For People Who Need to Fill 6.8L Tanks Or Need More Air In General

A fellow asked me that if the GX CS4 high pressure air compressor is an upgrade then why are both the CS3 models (the one with the external 12 volt power supply and the one with an internal integrated supply) still being sold on Amazon. I explained in my email back to him that the CS4 does have a longer run time and a faster fill rate but it’s not a replacement. I figured I better expand on the email because if one person is wondering then others are as well – the models are for people with different needs and budgets.

The CS3 series will work great for anyone filling either a small airtank like my 18 cu ft Omega, or an airgun directly. It’s light and portable so you can do that no problem. The limiting factor is that it is air cooled and has a 20 minute duty cycle after which it needs to cool down. I bought mine in November of 2020 and used it right up until I bought my CS4 in January 2023 and I am certain one reason it held up so well is that I would never run it for more than 20 minutes. If I was filling something that took more than that, I would run it for 20 minutes and then let it cool down. It could top off my Hatsan Gladius or FX Impact Compact Mk.II in far less time than that – it was filling/refilling the Omega bottle that took longer.

The CS4 notably has a water/fluid cooling, the ability to add grease every 4-6 hours of run time, a more powerful motor, a faster fill rate and the ability to compress air up to 400 bar (5,801 psi) and a detachable air line. Yes, it does reflect a lot of lessons learned by GX but it’s not a replacement of the CS3 – the CS3 is still there for folks who want a smaller and lighter unit that is more portable and aren’t filling bigger tanks.

I bought the CS4 because I am getting into some airguns that use a lot of air – a Gauntlet .30 and a Leshiy 2 in .22 so I bought a 6.8L Air Marksman carbon fiber tank. You may be wondering how is a .22 an air hog – well, it gets 28 semi-auto shots and then needs to be topped back off and it’s onboard reservoir is rated at 300 bar. I can fill it one time from the big bottle and then the bottle is close to 250 bar plus I plan on buying the bigger optional air cylinder for the Leshiy.

My point is that all of these were going to require the air pump routinely running longer than the recommended 20 minute duty cycle so I really needed to make the move.

In short, the CS3 is for folks who need a compressor to fill and airgun directly or small bottles plus save a little money. The CS4 does have newer technology and is for users who want to fill airguns directly plus have a long enough duty cycle to fill up to a 6.8 liter tank. I bet it could do bigger as long as you honored the remarkably long 5 hour duty cycle of the CS4 but I’ve not used it enough to say that. The CS4 is more expensive than the CS3.

Here are posts I have written about the CS3:

Here are posts I have written about the CS4:

Here are photos of the units side by side:

The CS4 is the larger compressor
You can see how the CS3 on the left has an attached air line vs. the CS4 that has a Foster quick connect for r aremovable air line.
CS3 is air cooled. You can see the large fluid filled finned cooling jacket on the CS4 through the vent holes.
CS4 weighs 29 pounds
CS3 weighs 19.4 pounds
When I bought the CS3 they did not have the integrated power supply model. I would have gone with the external supply regardless as you can hook your compressor up to a vehicle if you need to refill something in the field or at the range. On the other hand, the integrated model is even more portable as you don’t have to move the 12 volt adapter around.

Summary

I had to buy these compressors with my own money and these posts were not paid for – I want to be clear about that. My experiences with both the CS3 and the CS4 have been very positive and I have no reservations recommending either to you.

Oh – also – a guy emailed me the other day asking me about the GX CS2 and I had to tell him that I do not have any experience with that model. Folks, I only have these two. Before the CS3 I had a Hill Mk. IV hand pump – the Hill was excellent but that’s the limit of my high pressure air compressor experience. I am a licensed SCUBA diver but always bought my air at a dive shop so I had a little knowledge from that plus many, many years of industrial and shop pneumatic work but that was only up to 175 PSI.

Here are the GX compressors from the CS4 down to the CS1

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Understanding how an automatic folding knife works – Kershaw Launch 1 Disassembly and Re-Assembly

In the last post, I showed you a bunch of photos of the Kershaw Launch models 1 and 13. In this post, I am going to take the Launch 1 apart so you can see what it looks like inside. So, let’s get into it.

Tools Required

You will need #6 and #8 Torx bits. Something to pry the blade up and tweezers might help. For me, I have a large Strebito tool kit with a ton of precision bits, handles, tweezers and pry bars designed for electronics that has worked amazingly well for me when working on stuff with small fasteners.

Disassembling the Launch 1

Safety brief: Just remember, you are working with a very sharp spring loaded knife blade. It wants to open. Handle it accordingly and play it safe.
All of these screws use a #6 Torx bit. I removed the clip first and then the three screws holding the handle halves together. Note how the axle bolt is held in place by a hex head on the left. You don’t need to do anything from the side with that bolt – I’m just pointing out it is nice and secure. If you look at the screws at the bottom – especially the one to the right, it looks like some medium strength thread locker was on them.
I missed it on first glance – this is the other half of the axle bolt – kind of like a Chicago-screw or post-screw. I saw the decorative half circles and wondered how they removed it and then I noticed the hole in the center and looked more closely with a flashlight – hidden down in there is a #8 Torx screw.
There must be some thread locker on this as it took some torque to break it free. I didn’t need to use a wrench or heat – I just had to turn more firmly and it came loose.
Looking at the white/grey stuff in the threads – there probably was just a bit of threadlocker to keep it from coming lose but I am not certain. I would tend to think there is because you can’t crank that screw down or the pressure will keep the blade from opening.
At this point, all fasteners have been removed. Notice how I have it turned over so the push button is up – you will want to do the same.
So the scale lifts straight up and off. It is a snug fit on the axle bolt so it may take some wiggling to get it off. Now I need to point something out – look how clean the machining is and the finish is consistent. So many tools and knives look like crap inside due to an “out of sight out of mind” mindset that it is refreshing to see how well this is done. Kudos to the folks in the Oregon Kershaw plant!
The top pin to the left of the push button is hand press fit in place. Pull it out first and the blade will want to rotate clockwise and then the big hole will present itself to the push button and the push button will lift out.
Yes, in the photo above I said remove the pin and then the push button. In my case I was taking pictures and wiggling the blade round – the push button came out on its own. At this point the spring tension is being taken up by the pin. It’s not a crazy amount of spring tension the blade open but it is trying to go a bit further so be careful. This photo also lets us see the removed push button assembly. Normally, the fat bottom portion is engaging one of the cut outs in the bade. Either the one at the top that is keep it closed or the one at the bottom that locks it open. When you push the button the fat piece slides out the way and the blade is released to either open or close. Note, the spring is not sitting properly in the base of the push button in this photo.
I would not have needed the little blue pry bar if I knew the stop pin simply pulls out. If I had slightly closed the blade to take the pressure off the pin, I could have easily lifted the pin out, then controlled the few more degrees of rotation the spring had left in it and the blade would have lifted right off.
The torsion spring is what provides the power to flip the blade into position. The act of the user closing the blade rotates the spring’s coils and store the energy waiting for the button to be pushed spring back into the relaxed position. One leg of the torsion spring sits in the channel of the handle and the other sits in the blade. In this photo I have laid the blade 180 degrees opposite of how it normally sits in the handle so you can see how the torsion spring sits in the two parts. It’s elegant. Notice the ample grease – I think it might be silicone grease. Anything that causes the blade to bind will slow or even stop deployment.
Here are the parts and you can see the nicely done flat torsion spring. Again, I should have removed the stop pin, then the push button and the blade would have lifted right off the axle bolt. This is it other than removing the stop pin which plays into re-assembly.

Re-Assembling the Launch 1

Putting it back together is pretty straight forward. In hindsight I would tell you if something seems complicated, you missed something. That was exactly my thoughts as I was trying to the the torsion spring oriented with one leg in the handle and the other in the blade.

I spent about 5-10 minutes trying to get spring in and had my “duh” moment. Given how the spring sits, no tool so going to fit in there. I thought to myself “I wonder if that that stop pin can pull out?” And it did.
Wow!! Removing that stop pin made it sooooo simple. Rotate the blade such that the torsion spring legs are seated and you will feel the spring working. Then put in the push button and its spring followed by the stop pin.
I wish they designed the spring to snap into the button but they didn’t. An old trick that I used here was to fill the cup of the push button with silicone grease. The grease in turn holds the spring while you install the assembly.
Rotate the blade just enough so you can install the push button in that first large semi-circular opening. You can then push the button down and rotate the blade into the next notch which is the normal lock open moment. In this photo the blade is at a funny angle because the stop pin has not been installed yet.
Notice the blade is pushed all the way down on the axle bolt. To install the stop pin, push the button, carefully close the bade and release the push button. It should engage and hold the blade in the closed position. This presents the hole for the stop pin wonderfully as you can see in the photo and you aren’t fighting the spring. Literally, the pin goes right in.
I put a light coat on silicone grease on this side of the blade as I had wiped most of it off fumbling around. I did clear the silicone out of the bolt if you are wondering. You can also see the stop pin is in its hole.
The handle half is reinstalled. I carefully held it in place and tested to make sure the blade still pivoted and the push button worked.
When you reinstall the end of the axle bolt, you will need to see how much to snug down the screw. I found that if I made it too tight that the blade would not fully deploy. After experimenting, you may want to put just a bit of medium thread locker on the screw to keep it from working loose.
Re-installed these too and with that am done.

Summary

Kershaw did an excellent job on this knife. I thought about doing the same with the Launch 13 and it looks to be the same mechanism so I didn’t bother.

If you are looking for an automatic knife, I am very impressed by the Launch 1 and 13. I suspect the whole line has similar workmanship. I’ll post links further below.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Reviewing the Kershaw Launch 1 and 13 Automatic Knives

Growing up as a kid in the 70s and 80s you’d see some guy in a move whipe out a switchblade and you’d know a world of hurt was coming. For years, I wanted one but couldn’t own one. Now that I own two, I’m trying to figure out how they factor into my collection to be quite honest.

I’m not handicapped so I can’t speak to how they would use one but other than the “coolness” factor, I don’t see the point compared to the tons of flippers / assisted opening knives that I already own. To be clear, I am not bashing them but I won’t be buying any more either – my curiosity is satisfied. Please note – I am impressed by the design and the manufacturing but have decided they just aren’t my cup of tea.

With that said you are going to get my honest opinion.

Some Background

I like Kershaw knives in general so an ad for their Launch series of automatic openers caught my eye. I’ve always wanted to try a “switchblade”, or more appropriately termed an “automatic”, so I shelled out $114 for a Kershaw Launch 1 and $125 for a Kershaw Launch 13. I figured that would let me try a couple of different designs and they have a number of Launch models for you to choose from.

One thing that appealed to me with both of them is that they are made in the USA. Kershaw has a production facility in Tualatin, Oregon, that makes these models as well as a number of their higher end Kershaw and Zero Tolerance blades. Part of the premium pricing reflects being built in Oregon vs. China.

Note: You need to know the laws and regulations governing automatic knives in your area before you buy one. The American Knife & Tool Institute (AKTI) maintains a page that can help at a state level but you still need to confirm about your county and city just to play it safe.

The Launch 1

This is a good size knife. The slightly “humped” design enables it to fill your hand and be held very nicely. Let’s talk specifications:

  • Blade length: 3.4″
  • Blade profile: Drop-point
  • Blade steel: CPM 154 – it is a tough stainless alloy that also holds an edge fairly well while being moderately easy to sharpen
  • Blade finish: Black Wash
  • Blade thickness 0.121″
  • Closed length: 4.6″
  • Handle material: 6061-T6 aluminum
  • Handle finish: Black anodized
  • Handle thickness: 0.47″
  • Overall length when open: 8″
  • Weight: 4oz

Pros: Weight and size are good, blade flips open with a snap when you push the button, very nicely made.

Cons: I honestly wish there was a safety. This thing opening in a pants pocket is going to really suck fast. Kershaw says it is “low-profile” to make it harder to trigger but even so – you push that button and it will open fast.

Launch 1 closed. Like the US flag. Lines are nice, clean and flowing. All of the screws on this side are T6 Torx. The handle is 4.6″ long, 0.47″ thick, 6061-T6 black anodized aluminum.
At the left are the two screws if you want to move the ciip to this side. The axle pin the blade rotates on is held in place by a T8 Torx. You can see the recessed push button that does dual duty both to allow the blade to flick open and also to unlock the blade once it is locked open.
Good view of 3.4″ CP154 blade with a blackwash finish. The blade is 0.121″ thick so just under and 1/8th inch that would be 0.125″.
Here’s a view of the other side. Note how the axle bolt uses the handle scale to elegantly hold the hex head in place so you can tighten the axle pin from the other side.
From top to bottom: 1. Kershaw Launch 1. 2. Kershaw Knockout with a Damascus steel blade.. 3. Kershaw Blur and 4. ZT 0357. These are all excellent blades. My favorite is the ZT0357 and the Knockout. All are made in Kershaw’s Oregon plant with excellent machining, fitment and finish.

The Launch 13

I like unique looking designs and the Launch 13 immediately caught my eye due to the futuristic look and wicked Wharncliffe style blade. It looks odd but it actually fits my hand very surprisingly – better than I thought it would actually. Let’s look at the specifications:

  • Blade length: 3.5″
  • Blade profile: Wharncliffe
  • Blade steel: CPM 154 – same as the Launch 1
  • Blade finish: Black Cerkote
  • Blade thickness 0.121″
  • Closed length: 4.5″
  • Handle material: 6061-T6 aluminum
  • Handle finish: Black anodized
  • Handle thickness: 0.471″
  • Overall length when open: 8″
  • Weight: 2.4oz

So, it is just a tad shorter but quite a bit lighter than the Launch 1. With all of the angles and skeletonized scales, I didn’t think it would be as comfortable as it is.

Pros: Light, A Wharncliffe style blade

Cons: Even though the push button is recessed, I am fearful of it opening in my pocket.

The scales are nicely done and are machined from 6061-T6 aluminum with a black anodized finish. The small screws are all T6 Torx and the nut on the axle bolt is a T8.
You can see the push button that both allows the blade to spring open and to unlock the blade once it is open. Interestingly, the axle bolt’s head is triangular instead of a hex head like the Launch 1 uses.
The Wharncliffe-profiled blade is very sharp. Yes the grind is simple but it’s a Wharncliffe 🙂
Here’s a view of the Launch 13 open from the other side.
The Launch 13 at the top and the larger Launch 1 at the bottom.
Notice the different handle angles when you get the blades in about the same plane.
From the top: Kershaw Launch 13, Launch 1, ZT 0357 and Kershaw Knockout with a Damascus blade (they also make one that is not Damascus wo that’s why I am pointing it out)
And the other side from the top: Launch 13, Launch 1, ZT 0357, Knockout with a Damascus blade.

Summary

The Launch blades are very well made. Of the two, I am partial to the Launch 13 because it is lighter and has a Wharncliffe profile blade – again, I like Wharncliffes. I can cross having an automatic knife off the bucket list but plan to stick with assisted opening flippers like the ZT 0357.

Would I recommend either Launch knife to someone wanting and automatic – yes, I would. The build quality is definitely there. How can I prove it? In the next post I will take the Launch 1 apart and let you see it.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Bulgaria, Russia and also USSR

Amazing tour video of the Hind Mi-24 helicopter by a pilot

Folks, I have found the Russian Hind Mi-24 helicopter absolutely fascinating for decades. Both I and the Hind are old enough to truly say decades in this case as it was delivered to the Soviet Air Force in 1970 but NATO and the West didn’t find out about them until 1972.

The HIND is a huge helicopter gunship and unique in that it has room for eight passengers. At the same time it is fast, armored and loaded with weapons. Soviet pilots called it the “flying tank: and other nicknames include Galina, Crocodile/Krokodil and Drinking Glass.

At any rate, it is very interesting and has evolved over the years plus the Soviets and later the Russians exported it to many countries including Bulgaria, Macedonia and many others plus it has served in a number of conflicts (click here for the Wikipedia Mi-24 page if you want more details).

The purpose of this blog post is to share with you an amazing video assembled by Erik Johnston where Bruce Stringfellow, a Hind pilot, gives a detailed walkround tour of the helicopter. How detailed? It has an hour and 16 minutes of detail – it is the best video I have ever seen if you want to really know more about the design, capabilities and what a preflight check looks like from a pilot’s view. Here it is:

Note, the photo shown at the top is extracted from the video and shared under fair use. I do not own the rights to the video and imagery – the video was created by and presumably owned by Erik Stone Photography.

DIY - Do It Yourself, Home Security

Replaced Old Solar Home Security Lights – The New LazyPro 2500 Lumen Solar LED Lights Are Great!

In 2019 I installed some Lemontec solar lights around the perimeter of our house to get rid of dark areas and they have held up fairly well until now. One unit had quit working and other was coming apart so I decided to order some new ones and try a different brand.

A few months back I had to apply silicone glue to seal the bulging solar panel of this Lemontec light. Guess what? It still works great and I moved it to another area.
dCompared to the solar light above, this looked better but was dead. Rather than tinker with it, I put it in the trash.

As usual, I did some searching on Amazon and looked for ones with good reviews and found a brand called “LazyPro” – yeah, I almost didn’t try them because of the name but I am glad I did! They are sold in pairs and I replaced the Lemontec that had failed and the one next to it – because they are high traffic areas right by our driveway and also very dark at night.


You ever read something so off the wall that you just have to try it? That was my exact reaction when I read their slogan “We are engineers of laziness. We create gadgets that make life easier. With this Solar Lights you have more time for … whatever you like to do. Because we are too lazy to pay for electricity.” Alrighty … uhm … okay, let’s try them!
Out of the box they looked well made. This was right before I installed them.
I removed the old solar lights and mounted these new ones in their place. I set the switch on the back for dusk-to-dawn and to only turn on if motion was sensed. You do have other options such as turning on at dusk with a low light output and increasing the light output if there is motion.
The lights are just over seven feet off the ground and 12 feet apart.

What an improvement! The LazyPro units throw out a very wide volume of light because the LEDs are mounted not just on the front but also on the sides and bottom.

Also, the sensor does a really good job of picking up movement – the Amazon listing claims 40 feet and it easily does that if not even further.

This is the area with just our porch light running. It’s dark.
I walked in front to to activate both lights and you can see the huge volume of light the two units are producing.

Summary

Yeah, the LazyPro brand name might make you wonder but these are remarkably good lights. I plan to replace the other four Lemontecs that are still working but don’t produce anywhere near the same amount of light.

Miscellaneous

Visited Japan and saw the Japanese D51 #408 Steam Locomotive in April 2019

I grew up with my dad taking me to see steam engines, steam trains and all kinds of machinery. I’m sure that’s why I find these things so fascinating today. My day job has a fair amount of travel and sometimes I get to see some really cool stuff. I was visiting Tokyo with my wife in April 2019 and we met up with a friend from her childhood, Spike, who showed us around.

One of the places Spike took us was the Ikuta Ryokuchi Park in Kawasaki — I think it was about an hour and a half from downtown Tokyo by train. Ryokuchi is a big park with different sections. We had a great time walking through a exhibits of traditional farms (Minka-en). Outside of the planetarium sat a very nicely preserved D51 Japanese steam locomotive.

There are a ton of pages that can tell you about the D51 “Mikado”-class locomotives – they where built for the Japanese Government Railroad (JGR from 1920-1949) and later the Japanese National Railways (JNR from 1949-1987) by Kawasaki Heavy Industries Rolling Stock, Kisha Seizo, Hitachi, Nippon Sharyo, Mitsubishi and Mitsubishi Heavy Industries. Construction happened in two periods 1936-1945 and also 1950-1951.

In total, 1,115 D51s were built. They had a 2-8-2 wheel layout, were just over 64 feel long, and the locomotive weighed approximately 84.7 US/short tons. Maximum speed was about 55 mph.

The trains were retired in Japan in 1975 though they were used in the Soviet Union until 1979 and 1983 in Taiwan. [click here for more information on Wikipedia plus this is a very interesting page in Japan]

The park is very much worth visiting and it was very cool to see this D51 up close.

How loud is a GX CS4 Compressor? It’s not bad at all – what I also learned is that cheap sound level meters aren’t consistent

There’s an old saying that nobody is sure of where it came from that says if you have one clock you know the time. If you have more than one, you are never quite sure. The reason for this is that if the clocks have different times then which is wrong or right? Well, I guess now we have time servers, atomic clocks and what not to help answer “what time is it?”.

Now why did I open with that? Well, the only sound level meter I had to measure the decibels of anything was my phone and two different apps that kind of agreed. When reading reviews, folks would say that phone sound level apps were not accurate. Well, I decided to buy a sound level meter to be more accurate … that was in 2017 and I thought I knew how many decibels things were using my cool BAFX3608 meter.

Fast forward to February 2023

I decided to test my GX CS4 and I also wanted to test some airgun moderators so I thought I would order in a few more inexpensive sound level meters to get readings in different spots – a BAFX3370, a Tadeto SL720 and a XRCLIF-1359.

I was using my GX CS4 compressor to top off my 6.8 liter carbon fiber bottle and thought it would be a great time to get sound readings from relatively the same location. I lined them up and took a video to capture sound readings on each meter at a certain time by freezing the video.

Here’s the video so you can hear the compressor and see the meters:

How did they do?

Well, I recorded the readings at 4,11, 16, 21, 26 and 31 seconds. I then calculated the average of the four and compared the meters to the average. The BAFX 3608, BAFX 3370 and XRCLIF were closest. The Tadeo was introducing quite a bit of variation into the samples. With one exception at 26 seconds, it always registered the lowest decibels. Excluding the Tadeto, the average spread was 2.97db across the three meters. With the Tadeto, the average spread increased to 6.8db.

By the way, the manufactures claim +/-1.5db of accuracy for the two BAFX meters, +/-2.0db for the Tadeto and +/-1.5 for the XRCLIF. That means the ranges should have been at most 3.5db apart. The recorded data showed spreads far wider than that.

What this spread tells me is that the two BAFX units and the XRCLIF are in relative agreement given their stated accuracy. My tendency is to think they are closer to whatever the real measurement actually is and discard the Tadeto data. It also tells me that when you buy cheap uncalibrated sound meters you get cheap uncalibrated sound meters.

What about the apps?

I tried the both the “Sound Analyzer” and “Sound Meter” apps for my Samsung Galaxy S20FE. The Sound Analyzer reported an average of 79.3 and the Sound Meter app averaged 80. The sampling was done by holding my phone about the same distance from the CS4 and letting each app collect data for about 30 seconds. Given how fast the CS4 pumps, the apps had quite a few cycles to record.

This is a screen capture of the Excel file I created to look at the data.

Conclusion

I have a vague idea that the average sound level was somewhere between 81.5 to 86.1db as the machine operates if I exclude the Tadeto’s recordings. The samples were drawn at different times and the pump had a repetitive rhythm to it so I am sure the volume did differ but looking at the spread across the meters and the deviation from the average tells me that three meters are closer to one another (the two BAFX models and the XRCLIF) and the Tadeto is an outlier. The apps don’t really agree with anything either.

To wrap it up, thanks to my PC periodically synching its clock to a time server, I know it is about 9:20pm right now. What were the actual sound levels during each of those samples … now that I don’t really know with any precision – I have a ballpark range. I guess some day I will need to buy a quality calibrated sound level meter – what I probably should have done from the start. If you need to buy a meter and can’t afford a higher end unit – buy either the BAFX 3370 or the XRCLIF-1359. The BAFX 3608 is no longer made (as mentioned – I bought it back in 2017).

Here are the GX compressors from the CS4 down to the CS1

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
